DELINTING DRYING TUMBLER.

Application filed April 23,

Tb all whom it may concern Be it known that I, EDMUND I. CUTTER, acitizen of the United States, residing at ing to remove the lint fromthe air after its passage through the drying chamber.

The type of device to which this invention applies, as for instance thedrying tumbler, comprises in general a heating chamber, a dryingchamber, and an air chamber, a fan being located within the last namedchamber for forcing a current of air through the heating chamber, thencethrough the drying chamber, whereinis contained the laundry to be dried,and thence back to the air chamber; from which point the air might beexpelled from the machine casing or part of it recirculated through themachine. These several chambers have communication with each otherthrough pas-' sages which, in the present type, are controlled bydampers operated from the outside of the machine so that air can beforced through the circuit just described during the time of drying thelaundry, and by proper manipulation of the dampers the heating chambercan be eliminated from this circuit with the result that the freshoutside air is forced through the drying chamber and back to the airchamber for'the purpose of cooling the laundry before its removal fromthe tumbler. This particular type of device includin steam pipes 30 andba-flie plates 35 will he more fully understood from the description setforth in the Patent No. 1,424,994, granted August 8, 1922, to thisapplicant.

It havingbeen found that more or less lint from the laundry is picked upby the air in its passage through the drying'cham her, it has beendeemed desirable to remove such lint from the air before its return tothe fan chamber or before its return to the air of the room in which thedrying chamber is located. The means devised by ap plicant foraccomplishing this purpose is located within the air chamber and is incommunication with the drying chamber. By

prevented from 1920. Serial No. 376,135.

embodying this invention in the several types of drying machines, itwill be ossible to keep the lint out of the fan, the lint will bepassing through the rest of the machine and will not be allowed to passto the atmosphere ofthe room in which the machine is located and whereemployees are engaged at work. Other advantages will be apparent tothose who are familiar with the art.

Diiferent forms of structure out applicants invention will suggestthemselves to those skilled in the art, but the form preferred byapplicant will be under stood from the following detailed descriptionand claims when considered in connection with the accompanying drawing.

AMERICAN LAUNDRY for carrying Fig. 1 1s a vertical transverse section ofthe combination in which is embodied applicants invention; Fig. 2 is atransverse vertical section through the 'delinting device; and Fig. 3 isa detail View partly in section of the valve used in connection with thedelinting device. v

By the action of fan 4. which is covered by casing 5 within the airchamber 2, fresh outside air is .drawn through chamber 6 and forcedthrough passage-way 7 when damper 8 is in the full line position asshown in Fig. 1; thence through the heating chamber 1- in which arelocated steam pipes 30, through passage-way 12 when damper 11 is in openposition as shown in full lines in Fig. 1, to the drying tumbler 13which has a wall of foraminous material. After passing through thedryingchamber the air is forced back to air chamber 2, from whichchamber it is expelled from the casing through outlet 34. The tumbler 13which is given rota motion back and forth is also provided wit' bafliemembers 31 and a door 33 through which access may be had to the laundryupon opening door 32 mounted on the main outside casing of the machine.

WVhen damper 8 is in open full line position as indicated in Fig. 1, andas above redotted lines in Fi 1 so that fresh outside air is then drawnby the fan from chamber 6 throu h passage-way 9 to thedrying tumbler, wence it is forced through passa eway 14 back to the air chamber 2 and tot 1e outside atmosphere through outlet 34. In either case, as will beseen from the drawing, the air as a result of its passage through thedrying tumbler 13, will gather more or less lint from the laundry. It isproposed "by applicant to remove this lint by deflectout througiopenings 38 and 39 in the side wall of the machine casing, as seen inFig. 2. The lower edge portion of plate 16 extends slightly withintrough 19 and is deflected toward the drying c amber, as shown in Fig.1, thereby forcing the air to be again deflected from the near side ofthe trough .andin this way cause the air to pass over.

practically the entire surface area of the fluid body. The comparativelyrestricted passage between plate 16. and wall 17 will give suflicientforce to the air to cause the lint to be deposited upon the surface ofthefluid body. This trough member 19 contains a fluid to a 'oint justbelow the lower edge of plate mem er 16 so as to leave a passa e-way forthe air from the lower end of t e passage 15 to'the air chamber 2without forcing the air throu h the water in trough 19. Any suitable uidma be used, water having proved very satis actor According to aplicantsinvention the int will be deposited 1n the fluid contained'in trough 19and the air allowed to pass into air cha ber 2 free of such lint, whichaction corres nds somewhat to that of a filter. Sincemost of this lintwill remain upon the surface of the fluid in trough '19 it will be drawnoff throu h over-flow pi e 23, as better indicated in Fig. 2, and t enceout through discharge25 when the valve 24, shown n Fig. 3, is in theposition there indicated, a continuous supply of fluid being receivedthrough inlet pipe'20 so that'there will normally be a constant flowthrou h the tro gh. That portion of the lint whic sinks to the bottom oftrough 19 may be removed through pipe 22 whenvalve 24 is inposition toallow communication of the pipe 22 with discharge pipe 25, which valveposition may be obtained by turning handle 26 so as to bring its lowerend against stop 28. By turning handle 26 so as to come against'stop 27the valve 24 ma be positiened as indidicated in Fig. 3. Vihth a constantfluidsupply throu h inlet 20 it will be clear that the lint will ereadily removedfrom the bottom of the trough 19 u on proper setting ofthe valve 24. It will e apparent that the level of the fluid'in trough19 can be regulated by adjustment of valve 24.
